It really doesn't look like much does it?

That's also why I am being lazy and making the frames in a single piece, rather than like CrazyCraig who is making floors and futtocks.
At our scales that would get really fiddly

It was fiddly enough at 1:16, I had to nest several pieces together, sand the inside of the top one on a spindle sander, cut the top one off then proceed to the next. Then I had to sand the outside of each piece on a disk sander without sanding too much off my fingernails, I only had 3mm to hold on to. All done now but it's a tiny pile of matches for a lot of work.

Difficult to tell from the photo, is that stem laminated

Unfortunately yes, I didn't have any bent trees

It's simply a bit big and as it turns through almost 90 degrees the cross grain would be just as obvious as the laminations, or that's my excuse.

All the floors and futtocks have been shaped, next I have to drill and 'bolt' them.

Keel has been scarphed:

How on earth did they do that with an oak tree?  

Initially and for larger timbers they found trees that had partly fallen over and continued to grow. Later, for smaller timbers they tortured them in diabolical machines.

Michael, you might look at using this schooner as a template, she is roughly the same size and date.

She has a room and space of 24 inches versus your 22. Scaling the timbers and spaces (sided) down to suit gives:

Floor ..................... 5 5/8"
1st Futtock ............5 3/8"
2nd Futtock............5 1/8"
3rd Futtock.............4 7/8"
4th Futtock.............4 1/2"
Top Timber.............4 7/8"
Stanchions Heel.....4 7/8"
...................Head...4"

Believe me I have looked round the garden for suitable twigs or branches.

You should have started putting 'bends' in twigs twenty years ago.

I can see why they used floors and futtocks on the real thing

They also used bent trees, modelling woods tend to come with straight grain so many of the futtocks will have short grain at some point.

Nice going Craig

Slow going Tim, welcome.

Scarph, keel to stem, done. I'm happy with it. Stem still needs to be sanded to width.

A tiny update. The jig is complete and dry fitted but I'm not going to glue it until I'm sure I don't need to change it. Frame production is underway (strange, I could swear I'd made three times as many as I have).

I won't have to clean the pritt-stick off the wood

If you do, just dampen the paper with a cotton bud (Q-tip) and it will peel straight off. It will leave a glue residue which will need to be washed off (again with a cotton bud). Practice on some discards.

Has anyone tried this?

No, but I'm going to.

Ok, glue needs to dry.

Tim, your extensions might be a little long. You need to be able to clamp in as well as down:

And when you are doing it for real, sand the planks before fitting them, particularly the inside.

Some progress, luckily I realised I needed to leave tabs sticking up from the moulds to hold the floors in place:

Craig, I printed out your scale, but my printer got it wrong and it came out slightly oversize. I could probably solve that problem but I don't have the patience to argue with a printer.

Michael, when you go to print there will be a size or scale option. The default is probably something like "Fit to page" or "fit to Margins". You want the option that allows you to set a percentage like the "Custom scale" option in the screenshot.

Print first at 100% and check the print for size. If it's wrong then "measurement I want" divided by "measurement I got" times 100 should give you the percentage to print at.

It's been too hot to cut wood so I separated out the floors and futtocks which I had forgotten to do.

Yes yes, yet another Bounty Launch. This will be the third being built at the moment.

And this one at 1:16.

As far as I can see these are the first scratch built Bounty Launches on this forum excluding those built for Bounty models.

Allan has been asking lots of questions in preparation for his build which has driven much research and given us some facts to work from. https://modelshipworld.com/topic/33217-bountys-ships-boat-details/?do=findComment&comment=945945

We have settled on building based on ZAZ7361 with some minor tweaks:

https://modelshipworld.com/topic/33217-bountys-ships-boat-details/?do=findComment&comment=948363

We have each done our own drawings and I have now reached the stage where I can start building in earnest. I have made a few pieces but wanted the jig designed before starting this log.

We shall see how it goes.

she departed with two sets of steel or metal removable davits closer to the bow

Those are very nicely done. A worthy addition.

I do love the look of wood in it's natural state

You tempt me to do a 1:24 in Huon Pine. Depends on how the 1:16 goes.

Craig : your ZAZ7361 dxf loads perfectly

Good to hear. I took a break from the drawing. I now have frame H, a keel with deadwood and sternpost and a piece of laminated timber for the stem. But before I can scarph the stem to the keel I have to finish the frame drawings so I can design the building jig.

So back to drawing soon.

Should all of this information also go on the other thread Bounty ships boat details  as well ?

it would keep all of the more technical stuff in one place so others can find it.

It will later, it's not finished.

Its the line indicated by the red arrow.

Ok, I thought it would be that one.

It's one of the diagonals. Measurements in the table of offsets (which we don't have) give the length along the diagonal from the centreline to the station line this is sometimes longer than the (half) width of the hull.

On my drawings I (try to) make the same reference line the same colour wherever it appears.

I can now use yours to trace the keel and plan so it will all fit together.

what does the dashed line ( marked with red arrow ) outside the hull line on the plan represent?

Did you identify this line? I'm not sure which one you mean.

These may be of more use (bigger image in the zip file):

Still deciphering these drawings, what does the dashed line ( marked with red arrow ) outside the hull line on the plan represent?

This is the dxf (re-imported into vectorworks). It's changed some line colours and but I think that's all (size difference is due to printing 'current view').

Re-imported:

When I import your DXF to fusion, there are loads of control points, that really bogs down fusion so it not usable. Which program was it drawn in ?

An old version of Vectorworks.

Sounds like I better stick to images or PDFs.

Let me know if this helps.
